Alternator is not the problem (alternator = generator btw).

Change your electrician before he frustrates you. Find a competent tech who knows voltage reading very well.

Thanks bro. Can u suggest a reliable one in lagos?

Dottore:
Alternator may not be the problem. This is probably another case of wrong diagnosis. In my humble opinion I'd suggest that you try and use a different battery for 3 days and see if the problem is solved. Some batteries may develop fault without you being aware irrespective of the fact that they still look new.

If the problem continues then have a good electrician inspect the car electrical wiring and electronics gadgets carefully to see if there's any gadget that is not turned off when the car ignition is off.

One or more of the Relays/modules that control the supply of electrical power to the electronics may have developed fault:
The car stereo, windshield wipers, headlamps, traffic actors, inner light, break lights, etc.

The crankshaft belt roller might need to be checked or replaced

If the problem persists then their could be a logic problem from the brain box. Have them test another brain box on the car.
Good luck.

Where is the roller located cos i have noticed that my belts have started squeeling. Even after putting two belts. He said he wants to replace one of the rollers

mayor2013:
Accepted. Bring it in with all Generators changed

what generators

mayor2013 help! Can u help me diagnose this car

GAZZUZZ:
replace harmonic balancer. Aka crankshaft pulley.

where is it located bro. can u post a pic. my mech said he would replace one of rollers that its making small noise. Can this cause the alternator not charge?

mayor2013:
150amps rather. You need to work with values here

1) battery voltage at rest
2) output voltage while car is ilding and all loads such as full lights, radio, hvac and others put on
3) out put voltage with no loads on

N.b: a voltage drop test should also be carried out

If i disconnect negative at idle. The car goes off even if i rev it. The worst is if i put on the ac. It starts killing the battery and within 1 minute the car would stall

Dottore:
Try and use a different battery for 3 days and see if the problem persists

It has killed over 5 batteries. im frustrated

Good day Nairalanders,

I have had an issue with my charging system before it worsened to a bad extent which i had no choice but to replace my alternator just after I changed my compressor and condenser. I have changed 3 alternators but the same issue persists. I placed the highest alternator amp which is 150V but still the same thing. The car charges fine when in motion but stops charging the battery when its idle. It starts draining the battery fast. Pls advice. Is it a bad wiring or the alternator is defective? HELP!!!!
